Application'filed'May is. 1927. Serial No. 192,33s.

My invention relates to a device to be used parachute and carried on aerial machines. r V

The general object of my invention :is. to provide a device of the indicated character which is provided with'n'ovel means to 0bstruct the passage of 'air through the device in a manner to retard the descent of the parachute.

A further object of the inventionis to provide means whereby the'fiow of air through the: device may. be regulated in a -manner to conform to the. weight ofthe person descendingwith the aid of the parachute.

The nature of my invention and its dis-- 7 another form of the invention.

Figure 3 is a detail in transverse vertical section as indicated by theline 33 of Figure 2.

Figure .4 is a perspective view of the parachute collapsed into the folded form for V convenience when carrying or storing.

Referring first more particularly .to Fig-' ure 1 of the drawings, the numeral 10 indicates the bodywhich is rectangular in horizontal section to give it a box-like form.

Within the body 10 are central baffles 11 horizontally disposed and terminating at the ends short of the sides of the box 10. Spaced fromthe bafiies 11 andv alternating therewith are pairs of bafiies 12 extending from the side walls of the body 10 to a point short of the center. Thus a space 13 is produced between each pair of baffles 12 and spaces 14 adjacent the opposite ends of the baffies 11, whereby airv passing upwardly through the body 10 will be caused to alternately pass at the sides of the baiiies 11 and between the baffles 12.

In order that the user of the device may suspend himself from the parachute, ropes 15 extend from each corner and converge below the body 10 where they are connected by" rings, 16 or equivalent means to fasten'the harness worn by the person descending. At

posed edges to the top of the bodv 10 fixed top'sections 1 are provided spaced at their adjacent exoutlet '18.

' In. the form shown in igures2 and 3, the body designated 110-and corresponding in its essentials with the body 10, haselon'gated slideways 19 formed in corner. strips 20' suitably secured to the body 110. "Slide plates present an intervening air 117 are disposed above the outlet 18, as shown in Figure 2, and spaced to permit air passing from outlet 18 between said slide plates or shutters 117. 'The plates'117. are subject to springs 21 at the back of each plate, said springs tending to force'saidplates toward In order that the final air out 1 each other. 7 let may be varied to suit the weight ofqthe particular person descending, I employropes" 22. secured as at 23; tothe' slide'plates 1-1-7,

and extending downwardly along the sides of v the body 110, said ropes 22 being convergent as at 122, belowthe body 110, and in prack tice these ropes 122 are directed to any convenient point to be reached by the person descending, and suspended from the ropes 15 and ring 16. The ropes 2.2 may be suit ably guided on the body as shown by upper sheaves 24 on corner brackets 25, and at thelower corners of the body 110 sheaves 26 are provided on brackets 27.

The lowermost battle 28 is preferably inclined upwardly from the center to facilitate the entrance of the column of air in-itspassage toward the baffles 11 and 12 above.

In Figure 4 the parachute is shown when collapsed, the opposite sides. taking on the form of bellows folds.

. It will be readily understood that the parachute, in addition to 'bein used for the descent of a navigator, is use ul for dropping mail from an aerial vessel, or the dropping of packages in warv activities and war-inanoeuvres. I would state furthermore that whilethe lllustrated examples constitute a practical embodiment of my invention, I do not limit myself strictly to the exact details herein v illustrated, since, manifestly, the same can be considerably varied without departure fromthe spirit of the'invention as defined in the appended claims. 7 I claim: I 1. A parachute comprising an elongated body open-for the passageof air vertically therethrough, manually controlled means for regulating the passage of air through the scending with the parachute and top sections on the body presenting an air outlet therebetween.

3. A parachutecomprising'aboX-like body,

a series 0f horizontally disposed baffles extending across the center of the body and spaced at its ends from the walls of the body, and-a second series oi horizontal batfles extending from thesids Walls of the body between the first battles and presenting'a centralspace therebetween. v

4. A parachute including a body, horizontally disposed bafiles extending -across the center of the iloody andspaced at the ends from the Walls of the body, and a second .series of battles extending from the side walls of the body and presenting a central space therebetween; together with a baffie below the first and second mentioned battles and adjacent the lower :end of the body and inclined upwardly toward the side edges-from the center.

5. A parachute comprising a box-like body open at the bottom and having an outlet in its top for the passage of air vertically therethrougl1, horizontally arranged battles in the body and manually controlled means to vary the outlet of air at the top of the body.

6. A parachute comprising a rectangular body .e penat the bottom and having an outlet in its top for the passage of air vertically therethrough, guideways :at opposite (sides or" the body at the top, slides movable in said:

and from each other to vary the size otthe' air outlettherebetween, manually controlled means for moving said slides in one direction, together with springs tending tonneve the slides in the opposite direction andilrorizontally arranged "battles in the body.
